Taking pictures of the moon on a smartphone is a task that seems impossible without professional technology. However, despite the budget price category, the Xiaomi Redmi Note 7 can surprise the quality of images with the right approach.
In this article, we'll explore not only the technical aspects (surveillance, ISO, focusing), but also the nuances that are rarely talked about: how to avoid the lunar disk re-light, why stabilization is important even in daylight, and what applications will help improve the result. You will learn that shooting the moon on the Redmi Note 7 is better in RAW format - this gives 30% more detail in post-processing than JPEG.
Spoiler: You don't need a telescope or expensive accessories, you just need a regular camera, a few free apps, and a little bit of light physics, ready to turn a blurry spot into a detailed craterscape, then read on.
Why the Moon is Blurred: The Physics and Limitations of a Smartphone
The main problem when shooting the moon on the Redmi Note 7 β small-size matrix (1/2") And there's no optical zoom. The moon takes up everything. 0,5 It's a little bit arc-degree, and the smartphone sees it as a tiny dot. 2Γ) Quality drops sharply due to pixel interpolation.
The second enemy of clarity is atmospheric turbulence, and air currents distort light like waves on water, and this is especially true when you're shooting from the hand, because camera jitter increases blur, which is why professionals use monopods or tripods even for smartphones.
- π The size of the moon in the frame: at a focal length of 26 mm (equivalent) it will take up all ~100 pixels wide. That's less than it looks!
- π± Digital zoom: Redmi Note 7 zooms over 2Γ β This is a software stretching of the image with loss.
- π«οΈ Atmosphere: the lower the Moon above the horizon, the more distortion due to dense layers of air.
β οΈ Warning: Don't try to shoot the moon through a window! Glass adds glare and reduces contrast by 40-50%. Even a clean window distorts light waves.
Preparation of the smartphone: cleaning the lens and choosing the format
Before shooting, check the lens on the Redmi Note 7. Even microscopic dust particles or fingerprints scatter light, creating glare. Wipe the camera with a microfiber wipe (not paper!). Use Settings β System Apps β Camera β Clean the lens if you have one.
An important step is to choose the file format. By default, the camera saves the photo in JPEG, which compresses the image with loss. For the moon, it is better to activate RAW (if supported by your firmware):
- Open the Camera app.
- Touch the badge. βοΈ (setting).
- Select the image format β RAW (or RAW+JPEG).
RAW-file ~20 MB versus 3-5 MB JPEG, But they allow you to manually adjust white balance, exposure and sharpness without artifacts. RAW Free Snapseed or Lightroom Mobile app.

Camera settings: manual mode and optimal parameters
Automotive mode on the Redmi Note 7 will always overtake the moon, turning it into a white spot.
- Open the camera, swipe left to Pro mode.
- Set the settings: Focus: β (infinity). Shutter speed: 1/200β1/500 sec. (day) or 1/100β1/200 (night). ISO: 100β200 (minimum to avoid noise). White balance: Daylight (5500β6000K).
Why are these values? The moon is illuminated by the sun, so its brightness is equivalent to a sunny day on Earth. Long exposure (over 1/100) will lead to re-lighting, and high ISO will add digital noise.
| Parameter | Daytime | At night (full moon) | At night (sickle) |
|---|---|---|---|
| Excerpt. | 1/400β1/800 | 1/100β1/200 | 1/50β1/100 |
| ISO | 100 | 100β200 | 200β400 |
| Focus | β (infinity) | ||
| White balance | Daylight |
β οΈ If the moon is too dark, do not raise it. ISO β The noise on the Redmi Note 7 is already visible at the same time. ISO 400.

Use volume button headphones like a trigger: connect them to your phone and press the + button to shoot without shaking.
Stabilization: How to avoid tremors without a tripod
Even a slight tremor of hands at 1/100th of a second will blur the moon. Optical stabilization in the Redmi Note 7 is absent, so alternative solutions are needed:
- π± Then, put the elbows on a solid surface (table, windowsill).
- π§± Improvised tripod: a stack of books or a packet of rice (like a sandbag).
- π§ Voice control: tell me Β«OK Google, take a photo" (configure Settings β Voice assistant).
- β±οΈ Timer: Use the 2 or 10 seconds delay in manual mode.
For maximum stability, secure your phone with a money band on a flat surface (like a trash can lid), as long as you keep your lens looking exactly at the moon. Check the composition in advance: the moon is moving across the sky at ~0.5Β° per minute, so you only have 1-2 minutes per frame before it shifts.

Post-processing: how to pull details out of RAW-file
Raw images of the moon on the Redmi Note 7 often look dull. This can be corrected by processing in Lightroom Mobile or Snapseed.
- Contrast: Increase by +30β50 to highlight craters.
- Sharpness: Add +40-60, but donβt overdo it, artifacts will appear.
- Shadows: Reduce by -20 to darken the sky.
- Color temperature: Shift towards cold tones (4500β5000K) for a natural look.
To remove noise, use the Denoise tool in Lightroom (level 20β30). If the moon is over-lit, in Snapseed, select Correction β Shadows / Lights and reduce the light by -15.
Example before and after processing:
Original RAW: The moon is barely visible, the background is gray.
After treatment: Tycho and Copernicus craters are clear, the sky is dark blue.π‘
RAW processing provides 30-40% more detail than JPEG editing. Always shoot in both formats, if memory allows.
Additional accessories: what really helps
While the Redmi Note 7 is capable of taking the moon out of the box, a few inexpensive accessories will improve the result:
- πΈ Lens nozzle 10Γ (Xenvo Pro Lens: zooms in on the moon, but requires perfect focusing.
- π binoculars 8Γ42: Put the lens of the phone to the eyepiece of the binoculars (the method of afocal shooting).
- π₯ Mini-Statutory (e.g. Joby GorillaPod): Flexible legs allow you to fasten your phone to a railing or branch.
Budget life hack: Use a reading magnifier (5-10Γ) as an improvised telephoto lens. Stick it in front of the camera with tape, push it back 1-2cm and focus manually. The quality will be worse than that of specialized lenses, but the moon will become larger.
β οΈ Warning: When using external lenses, turn off autofocus! Manually set focus on the external lenses. β Adjust the distance between the lens and the lens.
Common Mistakes and How to Avoid Them
Even experienced photographers make mistakes when shooting the moon on a smartphone.-5 lapses and their solutions:
- Overlight: The moon looks like a white spot. Solution: reduce shutter speed to 1/500 and reduce exposure by -1.5 feet in manual mode.
- Blurred: Craters are invisible. Solution: Check focus (should be on β) and use a tripod.
- Color artifacts: The moon is yellow or green. Solution: set white balance to daylight (5500K).
- Noise: Grainy. Solution: lower your ISO to 100 and shoot in RAW.
- The moon's small size: it takes 1% of the frame, so you can cut it in the editor or use a nozzle lens.
Another common problem is autofocus, which is trying hard to focus on clouds or airplanes, and turn it off completely and put the camera in mode. MF (Manual Focus).
